Save Table in XML Automatically

Question

Hello,
I need your help...
I want to get in a oracle db one table in xml format. I saw that we have a ORACLE XML DB package, where I can run "select" to obtain tables in xml. What I wan to do now, it is to save the result in a windows folder automatically, for example each hour. Do you know how can I do that? any idea?
Best Regards.

If you can, could you give an example of stored procedure to save file in the server?Yes, here's an example :
1) Create a directory object
create or replace directory test_dir as 'c:\oracle\test';2) The procedure
CREATE OR REPLACE PROCEDURE getEmployees
IS
  xmldoc          CLOB;
  xmlprolog       VARCHAR2(80);
BEGIN
  -- builds the XML prolog using the database charset for the encoding
  SELECT '<?xml version="1.0" encoding="' || utl_i18n.map_charset(value) || '"?>'
  INTO xmlprolog
  FROM nls_database_parameters
  WHERE parameter = 'NLS_CHARACTERSET'
  -- generates the XML document
  SELECT XMLSerialize(DOCUMENT
           XMLElement("Employees",
             XMLAgg(
               XMLElement("Employee",
                 XMLAttributes(empno as "id")
               , XMLForest(
                   ename as "name"
                 , job as "job"
                 , hiredate as "hireDate"
               order by empno
  INTO xmldoc
  FROM scott.emp
  WHERE deptno = 10
  -- writes the document to a file in the directory TEST_DIR
  DBMS_XSLPROCESSOR.clob2file(xmlprolog || xmldoc, 'TEST_DIR', 'employees.xml');
END;
/When called, it'll create a file "employees.xml" containing :
<?xml version="1.0" encoding="UTF-8"?>
<Employees>
<Employee id="7782">
  <name>CLARK</name>
  <job>MANAGER</job>
  <hireDate>1981-06-09</hireDate>
</Employee>
<Employee id="7839">
  <name>KING</name>
  <job>PRESIDENT</job>
  <hireDate>1981-11-17</hireDate>
</Employee>
<Employee id="7934">
  <name>MILLER</name>
  <job>CLERK</job>
  <hireDate>1982-01-23</hireDate>
</Employee>
</Employees>(formatted)
